Yesterday I made an excel spreadsheet to calculate how many rounds I can make using the materials I have on hand (ie 1 pound of powder and 25 lbs of shot), or I can put in how many rounds I want to load and it tells me how much materials I need.

Not rocket science, but it saves some work. Just punch in how many grains of powder and how many ounces of shot and it does the rest. Super easy. I'll probably add some features to price everything as well. If anyone wants to take a look at it, I can email it to you.

If I have a POUND OF POWDER and need to know how many loads I can get out of it, I:

There are 7,000 grains in a pound. Divide 7,000 by the number of grains your load requires. After you have done that, SUBTRACT about 20% [for screw-ups/loss] and you have a figure to buy primers, bullets and cases from.

Exactly. And the spreadsheet is cool because it makes it real easy to play with the numbers. Immediately change the shot charge, powder charge. If you need to load 500 rounds of 1 1/8 shot, and 17.5 grains, how much powder do you need? Easy enough to figure out, just that the spreadsheet does it faster, and it lets you change all the numbers instantly without having to go back through and recalculate. It will also price the loads for you. Again, not rocket science just slick, and saves time.
